there is no one Figure into which _Alum_ is observ'd to be crystallized,
but may by this texture of _Globules_ be imitated, and by no other.

I could instance also in the Figure of _Sea-salt_, and _Sal-gem_, that it
is compos'd of a texture of _Globules_, placed in a _cubical_ form, as L,
and that all the Figures of those Salts may be imitated by this texture of
_Globules_ and by no other whatsoever. And that the forms of _Vitriol_ and
of _Salt-Peter_, as also of _Crystal_, _Hore-frost_, &c. are compounded of
these two textures, but modulated by certain proprieties: But I have not
here time to insist upon, as I have not neither to shew by what means
_Globules_ come to be thus context, and what those _Globules_ are, and many
other particulars requisite to a full and intelligible explication of this
propriety of bodies. Nor have I hitherto found indeed an opportunity of
prosecuting the inquiry so farr as I design'd; nor do I know when I may, it
requiring abundance of time, and a great deal of assistance to go through
with what I design'd; the model of which was this:

First, to get as exact and full a collection as I could, of all the
differing kinds of Geometrical figur'd bodies, some three or four several
bodies of each kind.

Secondly, with them to get as exact a History as possibly I could learn of
their places of Generation or finding, and to enquire after as many
circumstances that tended to the Illustrating of this Enquiry, as possibly
I could observe.

Thirdly, to make as many trials as upon experience I could find requisite,
in Dissolutions and Coagulations of several crystallizing Salts; for the
needfull instruction and information in this Enquiry.

Fourthly, to make several trials on divers other bodies, as Metals,
Minerals, and Stones, by dissolving them in several _Menstruums_, and
crystalizing them, to see what Figures would arise from those several
_Compositums_.

Fifthly, to make Compositions and Coagulations of several Salts together
into the same mass, to observe of what Figure the product of them would be;
and in all, to note as many circumstances as I should judge conducive to my
Enquiry.

Sixthly, to enquire the closeness or rarity of the texture of these bodies,
by examining their gravity, and their refraction, &c.

Seventhly, to enquire particularly what operations the fire has upon
several kinds of Salts, what changes it causes in their Figures, Textures,
or Energies.

Eighthly, to
